<p>Much of the geometry code in Octave is based on the Qhull
library<a name="DOCF12" href="#FOOT12"><sup>12</sup></a>.
Some of the documentation for Qhull, particularly for the options that
can be passed to <code>delaunay</code>, <code>voronoi</code> and <code>convhull</code>,
etc., is relevant to Octave users.
